20110066319 | GOOD CHECKING FOR VEHICLE WHEEL SPEED SENSORS - A controller for determining whether a previously-detected vehicle wheel speed sensor malfunction still exists. The controller includes an electronic, non-volatile memory, and an electronic processing unit connected to the electronic, non-volatile memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The malfunction monitoring module monitors the operation of at least one wheel speed sensor and generates a fault signal when the at least one sensor malfunctions. The failure handling module causes drive cycle information and the fault information to be stored in the electronic, non-volatile memory. The signal checking module performs a signal check on information from the at least one wheel speed sensor. A tell-tale indicator is deactivated and/or a vehicle control system resumes normal operation if the wheel speed sensor passes the signal check. | 03-17-2011 |
20110066320 | GOOD CHECKING FOR VEHICLE LONGITUDINAL ACCELERATION SENSOR - A controller for indicating whether a previously-detected, acceleration-sensor malfunction no longer exists. The controller includes an electronic memory and an electronic processing unit connected to the electronic memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The signal checking module performs a signal check after the malfunction monitoring module generates the fault signal. The signal check includes executing a signal check function with a longitudinal acceleration signal. Also disclosed is a vehicle including the controller, and a method executed by the controller. | 03-17-2011 |
20110066321 | GOOD CHECKING FOR VEHICLE YAW RATE SENSOR - A controller for determining whether a previously-detected vehicle malfunction still exists. If the malfunction is no longer detected in the sensor signals, a vehicle control system operates in a first operational state or normal operational state with respect to the previously-malfunctioning sensor (e.g., signals from the sensor are used to control the vehicle). If the malfunction continues to be detected, the vehicle control system operates in a second operational state or malfunction state with respect to the malfunctioning sensor in which the signals from the sensor are not used to control the vehicle. | 03-17-2011 |
20110068913 | GOOD CHECKING FOR VEHICLE PRESSURE SENSOR - A mechanism for determining whether a malfunctioning pressure sensor has returned to a normal or acceptable operating range. The mechanism includes controllers and methods that perform a “good check” on the sensor to determine whether the sensor has returned to normal or acceptable operation after a malfunction has been detected. When a previously-malfunctioning sensor passes the “good check,” warning lights (or tell-tale) indicators are shut off and systems that relied upon information from the malfunctioning sensor return to normal operation. | 03-24-2011 |
20110071723 | GOOD CHECKING FOR VEHICLE BRAKE LIGHT SWITCH - A mechanism for determining whether a malfunctioning sensor has returned to a normal or acceptable operating range. The mechanism includes controllers and methods that perform a “good check” on the sensor to determine whether the sensor has returned to normal or acceptable operation after a malfunction has been detected. When a previously-malfunctioning sensor passes the “good check,” warning lights (or tell-tale) indicators are shut off and systems that relied upon information from the malfunctioning sensor return to normal operation. | 03-24-2011 |
20110071726 | GOOD CHECKING FOR VEHICLE LATERAL ACCELERATION SENSOR - A controller for indicating whether a previously-detected, acceleration-sensor malfunction no longer exists. The controller includes an electronic memory and an electronic processing unit connected to the electronic memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The signal checking module performs a signal check after the malfunction monitoring module generates the fault signal. The signal check includes executing a signal check function with a lateral acceleration signal. Also disclosed is a vehicle including the controller, and a method executed by the controller. | 03-24-2011 |
20110071727 | GOOD CHECKING FOR VEHICLE STEERING ANGLE SENSOR - A controller for determining whether a previously-determined vehicle steering sensor malfunction still exists. The controller includes an electronic, non-volatile memory, and an electronic processing unit connected to the electronic, non-volatile memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The malfunction monitoring module monitors the operation of at least one vehicle sensor and generates a fault signal when the at least one sensor malfunctions. The failure handling module causes drive cycle information and the fault information to be stored in the electronic, non-volatile memory. The signal checking module performs a signal check on information from the at least one sensor. | 03-24-2011 |
